Question

Marketing

You will need to test both self-written sites in php, and sites on all kinds of engines, such as opencart / joomla / others. The task as a whole is simple - without unnecessary dancing and body movements to set up the display of various versions of the site / its individual pages to visitors, with the possibility of subsequent analysis of the behavior of visitors through Yandex or Google statistics services, that is, with the possibility of marking the whole thing with utm tags, probably, or how So - in general, you need to be able to later evaluate the effectiveness of one or another option using third-party tools, and not the capabilities of the framework and / or the site itself.
